[Touch-packages] [Bug 1584965] Re: [browser] scrolling uneven and queues up
I tried to reproduce the same bug on Arale but to me it looks somewhat ok. I am using lastest oxide. There has been some changes in upstream chromium which might resolved this issue(https://crbug.com/574343#c40). I can see similar janked scrolling when I use --disable-features=SchedulerExpensiveTaskBlocking Which was default in chromium sometime before. I feel bug should not occur in latest oxide.

[Touch-packages] [Bug 1584965] Re: [browser] scrolling uneven and queues up
Initial investigation: There seems to be a blocking of task by blink scheduler because of prioritization of other task. So this may be result of side effect of blink scheduler policy. Need to check more before any conclusion. I get this log on console thrown by blink scheduler while scrolling on slashdot.org qml: [JS] (https://slashdot.org/:0) Blink deferred a task in order to make scrolling smoother. Your timer and network tasks should take less than 50ms to run to avoid this.

[Touch-packages] [Bug 1584965] Re: [browser] scrolling uneven and queues up
I can easily observe the same kind of issue with slashdot.org on my krillin running rc-proposed: - browse to slashdot.org, wait for the main page to be loaded - tap on an article headline to open it - wait for the page to be fully loaded, tap the back button - flick the page once It seems that if I wait long enough after the main page has been loaded back (a few seconds), then the issue cannot be reproduced, so I’m guessing this is linked to loading/rendering not being fully complete by the time the flick gesture is delivered. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to webbrowser-app in Ubuntu. https://bugs.launchpad.net/bugs/1584965 Title: [browser] scrolling uneven and queues up Status in Canonical System Image: New Status in Oxide: New Status in webbrowser-app package in Ubuntu: New Bug description: I've noticed this on a bunch of websites, mainly on Arale but also on krillin, both running latest rc-proposed with and without oxide 1.15 The scenario is I'm on page A, navigate to page B, press back button, then try to scroll page A (flicking up).
